Worked on the satlantis-dev/api-client repository to address a critical issue in the Notes Retrieval API, ensuring accurate account-based filtering of notes. The solution involved updating the URL parameter from accountId to account_id, aligning with established API parameter conventions and preventing incorrect data retrieval. This change was implemented in TypeScript and focused on API integration, with careful attention to backward compatibility for existing clients. The fix was validated through targeted unit tests and code review, minimizing the risk of data inconsistencies. Throughout the process, the developer emphasized reliability and data accuracy, contributing to the overall robustness of the API client.
